To all whom it may concern:

Beit known 'that I, HERBERT A. CRox'roN,

a citizen of the United States, and a resident of Massillon, county ofStark, and State of.

Ohio, have invented a new and useful Improvementin Controllin Means forCombustible Gas Mixtures, of W 'ch the following is a specification, theprinciple of the invention bein@ herein explained and the best mode inwhich I have contemplated a plyin that principle, so as to distinguishit flom other inventions.

My invention relates to means for controlling the flow of and burning ofcombustible gas mixtures, particularl as adapted to meet therequirements of mol -drying The object of theinvention is toprovidecontrolling and burning apparatus which is eflicient in its o ration,economical in its construction an which will' occupy the least possiblespac v y Said invent on consists of means hereinafter fully desc bed,and particularly set forth inthe claims.

The annexed drawings and the following description set forth in detailcertain mechanism embodying the invention, such disclosed meansconstituting but one of'variousv mechanical forms in which 'theprinciple of the invention may be used.

In said annexed drawings, Figure 1 represents a front elevation ofapparatus embodying my invention. Fig. 2 represents a section of thesaid ap aratus, taken upon the planes indicated by ines 2 2 in Fig. 1.Fig. 3 represents a plan of the valve-casing and burner-nozzle, togetherwith the air-supply pipe connected therewith. Fig. 4 represents a detailperspective view of the valve controlling the influx of air from theair-supplypipe.

Running parallel with the wall Ao thev combustion-chamber, in which thei ted gas mixture is designed to be directe and upon the outside thereofis an air-supply pipe B. In the uppermost part of this pipe is anopening b, which registers with an openino' c in the lowermost part of acylindrical Vvalve-casing C, the direction of whose axis isright-angular with reference to the'axis of pipe B. Opening c issurrounded by a cylindrically concave flange c', forming a saddle, bymeans of which and screws c2 the casing is secured iirmly to saidpipe.The interior of casing C is bored out at c3 to form a cylindricalvalve-seat, in which is seated a .cylinl drical hollow valve C', havingits inner end casin C. Such inner end is caused to abut a she der c,formed in the casing, and the open, as shown in Fig. 2, and coaxial withthe l in the valves shell allowsA of communication between the interiorof the casing and the airsupply pipe, as will be readily understood.

The outer end of the valve is provided with a squared boss c7, which maybe turned by a wrench to turn the valve, and sov control the ow of airinto the casing. Above the casing is a gas-supply pipe D, which alsoruns' parallel with the wall A, and leading from the bottom of such pipeis a conduit D', which passes through an opening es in the top of thecasing and is provided at its extremity with a nozzle d. This nozzle islocated in a tube C3, which is screwed into the end of casing C andforms a burner-nozzle for the device. 'Nozzle d is held in position andcentered by means of screws c9 c. A valve d controls the flow of gas tonozzle d. As shown, the nozzle C3 extends into an opening a, formed inwall A. Air and gas may therefore be simultaneously blown into thecombustion-chamber and ignited, properly mixed.

By'means of the described construction it will be seen that the entireapparatus may be placedin close proximity to the wall and is arranged tooder the least possible amount of l Having thus described my inventi'onin de- .-tail, that which I particularly point out and distinctly claimis- 1. The combination with an air-supply pipe and a gas-supply pipeabove the same and parallel therewith, of a valve-casing disposed atsubstantially right angles to said airsupply pipe, said casing beingformed with a sadldle adaptd to seat iplon the exterior of sai air-su py 1 e an avm an o enm through said saddl) g P g interior ofthe casing, acylindrical valve having its axis coincident with the axis of saidcasing and controlling said opening, a burnernozzle secured to saidcasing in axial alinement therewith, and a gas-conduit entering IOO ecommunicating with the said casing and provided with a nozzle loi e ofsuch casing in axial alinement therewith and pr'o; jecting into theaperture in such wall, and a gas-conduit entering said casing andprovided with a nozzle located in said burnernozzle, said gas-conduitbeing 'connected with said gas-supply pipe.
